The Plants Description

The pseudobulbs are placed close together, shaped cylindrical and have obtuse apices. The pseudobulbs measure 3.75cm long and 6.5mm in diameter. The leaves are petiolate, the petiole measures 1.5cm long. The leaf blades are shaped almost linear and are abruptly narrowed at their acutely shaped apex. The leaf blades measure 10-15cm long and 4.75-10mm wide.

The Inflorescence

The inflorescence emerges from mature pseudobulbs. The peduncle measures 6.5-11cm long. The rachis is zig-zag and measures 12-18cm long. The flowers are spaced 3mm apart.

The Flowers

The flowers are light green. The dorsal sepal is shaped rhomboid-lanceolate and has an acute apex. The dorsal sepal measures 5mm long and 1.75mm wide. The lateral sepals are shaped obliquely oblong and have acute apices. The petals are shaped lanceolate and have acute apices. The petals measure 4.8mm long and 1.6mm wide. The petal margins are erose towards the apices. The labellum is vaguely tri-lobed, concave and measures 4.4mm long. The labellum’s base is shaped quadrangular and has small rounded side-lobes. The side lobes have erose margins and measure 2mm wide. The labellum’s margins are erose basally. The mid-lobe’s apex is shaped part ovate and acuminate. The mid-lobe contains a few minute trichomes and measures 3mm long and 3mm wide. The column measures 1.3mm long. The apical hood is shaped transversely quadrangular and has a minutely dentate margin. The stelidia grow from below the middle of the column and are shaped obliquely oblong. The stelidia are wider at their apices.
